NDS FWSD69 6-Inch Round Surface Drain Inlet with Plastic Grate for Flo Stormwater Dry Well System, Pack of 1, Black

I used this NDS Surface Inlet Drain on each of 3 NDS Dry Wells. It is true that the drain could be sealed to the top of this dry well but, the general rule is not to, to allow for ground shifting over the years (such as earthquakes, etc.). I checked with NDS. I didn't seal mine. I did read a lot of items on others reviews all across the Internet so I hope the following notes help others. I've seen where others built their own with piping. I chose to get these for reducing the time of the installation of 3 wells. Some people discuss about about grass clippings, dirt, etc. could gradually fall into the dry wells through this drain inlet cover's openings, which is true. Others made reference to the possibility of mosquitoes. My wife searched around what others were doing and settled on a modification of a good idea, which we applied. So, after we installed the inlet drains we went to our big box store and found a roll of screen fabric that was promoted as strong enough to last and not too fine of a mesh to disallow overflow, in the case of excessive rains. We avoided metal screening so the material was some kind of nylon or other material. We then bought some large clamps (they were called "adjustable worm duct clamps". We chose specifically a 7-inch size so that there wouldn't be any excess to trim off. We cut off a square section of the fabric mesh and draped it over an installed inlet top. We then clamped it, using a worm geared clamp. The clamp was positioned at just slightly lower than the very top of the drain. After that, it was easy enough to then cut and trim off the excess screen. I've mowed about a dozen times now and have hit and scraped some of these without any ripping of the screen so it was important to get a strong, durable covering for this purpose, even though it was expensive. I do realize that eventually the screening might need replacement, as I'm prepared to do with the roll of fabric and extra clamps in storage but I'm guessing it might be several years. Eventually, I'll gradually raise the ground level around the inlet drains so that I won't "bump" them any more while mowing. Hope this helps others.

I ended up not needed this and so returned it, but I can confirm that it fit the dry well as advertised. It is very heavy duty and I am confident it would perform as described. Only returned it because my plans for the dry wells changed, not due to a problem with the product.

Nice heavy duty surface drain that vits perfectly with NDS drywells but no hardware to secure it.

There’s no reason to exclude this when installing an NDS well. The install is as simple as placing on top of the well. I put some duct tape to hold it in place while I buried it. Works great at collecting water into the well.

Fits well and does the job. Feels like a high quality part. A little expensive for what it is. Fits the NDS Dry well perfectly.

This is a sturdy grate that doesn't clog with dirt and debris easily. Mounted on top of an NDS Flo-Well for air escape (allow water displacement from water flowing into the well), and overflow when there is LOTS of rain, and an additional surface level drain for typical rainstorms. This is a MUST for anyone installing a Flo-Well.

Fits the flo well perfectly but doesn't lock in very tightly. Durable.
